The motor brushes (except for squirrel-cage motor outside) conduction current sliding contact body. In DC, it also bears on the armature winding induction alternating EMF commutation (rectifier) task. Practice has proved that: the reliability of the motor is running, largely depends on the performance of the brush.

In operation, the brush should meet the following requirements:

Commutator or collector rings surface can be generated by the cuprous oxide, copper oxide, i.e., carbon graphite particles such as moisture absorption of the oxide film.

Brushes on the commutator or collector ring wear is small, and their long service life.

Electrical and mechanical losses brush small loss.

Does not soften thebrushless slip ring work, does not melt under the face does not appear on the motor hazardous sparks.

Brush work noise.

Brushes can meet these requirements, does not depend on the brush itself, but also depend on the factor structure of the motor, installation and adjustment of operating conditions, such as brush slip ring

From the mechanical industry itself , the impact of its development favorable and unfavorable factors coexist.

Favorable factors: financial costs and interest expenses which dropped significantly increase corporate macroeconomic environment has improved , which is conducive to enterprise financial cost control . Accounts receivable increase sales growth , though still more than the same period , but has ended up settling . This shows that the loan recovery , though still difficult , but the risk of excessive growth are under control. Inventory ( especially finished goods inventory ) increase of less than sales growth over the same period , has been reduced to a low level , indicating that "to stock " has achieved remarkable results . This created the conditions for future economic recovery machinery industry .

Unfavorable factors: domestic demand is still insufficient. Product price index this year has been sluggish . Key enterprises in January - October , despite the growth in cumulative orders , but the increase was only 8.58% , indicating that the weak recovery in the domestic market . Export situation is not optimistic , the overall trend is still weak , January - October total export growth of only 4.62 percent . Weakened by the impact of investment-led , heavy engineering , machine tool industry will continue to face market demand situation, the more driven by the automotive industry, the pattern has not changed.

The machine together is expected in 2014 , the machinery industry in the conventional power generation equipment, metallurgical and mining equipment, heavy machinery, general machine tools and other sub-sectors will continue to be in demand slump ; high-end machine tools, robots and automated production lines demand will rise ; construction machinery market will has warmed up, the ups and downs gradually return to normal ; automobile and farm machinery sales growth will gradually decline , but large-scale high-end market will more prosperous agricultural products .
